Foot and Knee Eccentric Cam Ascenders

I have several eccentric cam foot ascenders that can be used in rope-walking and other systems. Personally, I don't like any of them, preferring to float a Gibbs for rope-walking and not needing a foot ascender when forced to Frog.

I also have some commercial and home-made Mar-Bars. The Mar-Bar was developed specifcally for Inchwork climbing. I rarely inchworm and so I seldom use these.

People have used many different ascenders as knee ascenders in various climbing systems. The two I list here are unique commercial systems. One uses an ascender specifically designed to be a knee ascender. The other has a unique sling design.
